  1. One dictionary definition is that a lobe is "a rounded projection".

    So I think that's what you're looking for with the lobes. 4 lobes being 4 bulges in the core.

    I think "lobes" are different from "panels". I mention that because I think I've seen some people describing 4-panel onionskins as 4-lobed onionskins.

  2. Galen, did you mix up "naked core" and "coreless"? When I first saw the question I was thinking the same as you but now that ZZ has posted I'm like "oh right!"

    In Collecting Antique Marbles, Baumann allows for ribbon marbles to have either one or two ribbons. (He says it's debatable with 2 ribbons would count as a double ribbon or a divided core.)

    He also seems to apply the term "naked" only to the ribbon style marble - when there are no outer bands, like ZZ says. (So then would Baumann apply the word naked to a double ribbon?)

    And then the divided core has more parts inside. Baumann says the production style of the divided core is similar to that of the ribbon core. But a divided core is still considered a different type from a ribbon core.

  3. From Henry Hellmer's batch book. Has both iron and copper, and then more copper in the brass. And lotsa zinc.

    From one of the "Carnelian Opal Glasses" pages:

    Copper Carnelians for Marbles

    Akro Agate Co. 12-1-25

    H.T.H. OK.

    Sand: 1120

    Soda: 410

    Borax: 10

    Red Iron Ox.: 45

  4. I'm getting the feeling that they may have used the name "Carnelian" and "Cornelian" interchangeably in the early years. And maybe to them the name(s) would have applied interchangeably to both of the nontransparent red & white marble types available in the teens and 20's.

    That would make sense in that time, I think, because carnelian and cornelian are names for the same kind of stone. IIUC.

    Their Dec. 1914 Clarksburg ad says Red Striped Carnelian: http://i119.photobucket.com/albums/o151/modularforms/Akro/1914_12_ClarksburgAkro_Playthings_b.jpg

    And Hellmer's batch book gives a recipe for "Copper Carnelians for Marbles" for Akro Agate with a date of 12-1-25.

    But of course boxes and other ads we know of from that era say Cornelians.

    So maybe it was pretty much the same to them and they only made distinctions between the copper-based and non-copper-based types when it was time to mix up the recipe?
